Leave, just slowly stop being/talking with them. Is there anyone in your class that you might want to get to know or feel like can be a good friend? If you really want to FaceTime them it’s okay to take one step back, but try not to. Your mental health is very important, if you have terrible talk with someone you trust. Like some one in your family, cousin, parents, aunt. But if you have any family trouble, that’s okay is normal, you can talk with your teacher for example. I don’t expect you to trust me immediately, but if you don’t find anyone you can talk with me. <3 stay safe!
